5. Types of Hearing LossConductive hearing lossTemporary loss when the sound waves can’t get from the outer ear to the inner ear.Caused by fluid in the ears, ear infection, malformation of the outer/inner ear, etc.Sensorineural hearing loss (SNHL)Permanent loss when there is damage to the inner ear or nerveOtotoxic medications, heredity, genetics, and agingMixed hearing lossConductive loss causes SNHL to worsen

8. Hearing Aid TypesBehind the Ear Hearing AidsBone Anchored Hearing Aid (BAHA)
9. BAHA: How it WorksThe BAHA:The processor (box) “catches the sound waves” and sends the waves through the bones in the skull by vibrating. The sound waves go through the cochlea which turns them into neural signals and sends them to the brain.The brain interprets the signals as sound or what we hear.
10. How Does the BAHA Sound?To experience what it is like to have the BAHA:cup your hands over your ears talk at a normal volume and listen to yourself (not others around you)the sound you hear seems to come from inside your head No, you're not crazy This is similar to how the BAHA sounds when being used
11. Using The BahaCheck batteriesTurn on processor by pushing one of the outside buttons (on top)Listen for a ding ding ding and feel for vibrationsIf nothing happens then batteries need replacedChange batteriesTake the little screwdriver and turn screw to the up position (half a turn to the left)Slide down and pop off (from bottom)Lift flap and take out batteryPut in new battery
12. Picture Steps for Replacing Batteryhttp://www.cochlear.com/wps/wcm/connect/us/recipients/baha-4/baha-4-basics/baha-4-basicsUnlock by turning screw half turn to leftLock by turning screw half turn to right
13. After Battery ChangeReplace cover and turn screw to lockCheck batteries againPlace band on head with processors behind the earsLing 6 sound testHave child repeat each sound back to youm, ah, ee, oo, sh, sWatch child’s body language/reaction to you talkingYou will be able to tell when they can hear you
14. FM System or Blue Tooth MicrophoneYour classroom will have an FM system in the room with a personal microphone. Similar to the idea of surround sound or loud speaker. Everyone in room can hear.Supplied by districtBAHA also has a blue tooth systemPersonal (only wearer of BAHA can hear it)Speaker talks into microphone and the sound is carried via blue tooth to the processor
